Ticket Giveaway: Two Pairs of Passes to the Dallas Sci-Fi Festival

Attention nerds, dorks and assorted dweebs: You can get your photo taken with Doc Christopher Lloyd AND Lea Thompson this weekend at the Dallas Sci-Fi Expo! There are loads more of your favorites lurking -- some of those Battlestar Galactica kids will be on the loose. But most of us really go to browse the stacks upon stacks of comics and collectables while flossing in our finest tribute gear.

Want to arm wrestle Kevin Sorbo? Profess your love to Lea Thompson? Prod a "Great Scott!" out of Lloyd? Of course you do, and we want to help. We're giving away two pairs of tickets for Sunday at the Sci-Fi Festival. It's a great line-up, check it out here.

All you need to do is Like the Mixmaster on Facebook(the tenth add will win a pair), or -- if you already like us -- post a quick note on our wall stating which celebrity you're most thrilled to photobomb on Sunday.
